'WIRE FABRIC.,

To all whom 'it may concern Be it known that I, JACUB SGHWARTZMAN, acitizen of the'United States, residing `at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Wire Fabrics,

of which the following is a specification.

This invention relates to wire or metallic fabrics, the object of theinvention being to provide an improved fabric of this characterparticularly adapted for use in connection with spring mattresses andwhich will be simple in construction, durable in use, and comparativelyinexpensive to manufacture, made up of links quickly and inexpensivelyassembled, and in-which Vthe pull on the several links of the fabricwill be in a straight direction lengthwise ofthe fabric, while at thesame time the fabric will be unusually resilient owing to the peculiarconstruction kof the links. A

A further object of the invention is the Vprovision of an improved linkfor the body of the fabric. Y

A.` further object of the invention is the provision of an improvededge-forming link.

In the drawings accompanying and forming part of this specification,Figure 1 is a plan View of this improved fabric having one edge thereofprovided with the improved edge-forming links; Fig. 2 adetail view, fullsize, of one of the improved links for the body of the fabric; Fig. V8is an edge View of the link shown in Fig. 2;

Fig. 4 is a view, full size, of one of the improved edge-forming links;Fig. 5 is an edge the same form of links.

Similar characters of reference indicate corresponding parts throughoutthe several iguresof the drawings.

The fabric is made up of a series of interconnected links or units 2,each comprising a pair of relatively straight portions 3 and Y 4,running in substantial parallelism with Specification Yof LettersPatent.

wardly extending or laterally deflected angular portions 6 and 7, whichangular portions are for the purpose of interlocking or `'connecting onelink with its companion link in the manner shown at 9, which illustratesthe parts twisted as it were together, although this twist, as will beobvious, results because of the formation 'of thelinks at the points '6'and 7` in the manner shown and described. l In forming the angularportions 6 and 7 it vwill be lobserved that they are so bent that theportion 6 will be inclined or extend to one side of the plane of thelink, (see lforV instance the edge view in Fig. 3), being connected withthe portion 7 by a short upright bend V8, which permits it together withthe deflected formation of this portion ofthe link to be interconnectedin the mannerV shown at 9L Each link thus has a pair of what may be'considered as twisted parts or wires. Y

The fabric is thus made up of a series of N-shaped units which areconnected together, thus forming lengthwise extending Arows ofinterlocked links, this connection being aninterlocking one in all ofthe forms except that shown in Fig. 7, in which each pair of Nsshapedunits are connected by a ring. For reinforcing and strengthening theedge, the link shown in Fig. 4 may be used although this is notabsolutely essential, as instead of using such a link a metalstripattached at its ends to the usual cross angle bars to which thehelical springs are connected may be interwoven with the outer diagonalportions 5 along the edge of the fabric if preferred.

"When the several units or links have been assembled in the manner shownthey may be connected tothe cross angle bars l0 by suitable helicalsprings 1l for which purpose the ends of the several units may haveconnected therewith rings 12. When, however, the edge links 13 shown inFig. 4 are used, connecting links similar to that shown at 14 may beused to which the helical springs l5 may be attached. These edge-forminglinks 13 each comprise likewise a pair of lengthwise extending portions16 each terlninating in a hook 17 and which straight portions areconnected by triangular formed portions 18 and 19, the triangularportion of which i's formed in much the saine way as portion 8, that isto say the parts 1S and 19 are connected by an odset portion 21, shownmore clearly in Fig. 5.

In Fig.V '7V instead of the N=shaped units being connected byinterlocking directly,for instance in the manner shown at 9 in F ig. 6,they are connected by means of a ring 22,

which however is interlocked with 'the twisted units of the links. Itwill be Vobserved that by means of the present improvement the pull onthe links is Y in a straight direction lengthwise thereof and on thestraight portions 3 and 4 thereof, and it will also be observed that thehelical springs may be attached at the terminus of ,i each straightportion, that is to say Vat the Vvpoint where the hook 3 or 4i is formedaccording to the way that the links are assembled, and at the pointwhere the loop 6 or is formed. When the links are assembled 1n themanner` shown in Fig-,1 the helical spring is connected to a link at thehook por'- tion 3 and to a pair of the` same links at the interlockedloop portions 6. Y

Thus it will be observed that both ends of the fabric are formed, andconnected alike,

for the connection .of the Vhelical springs, that is to say the fabricby being formed in the manner shown does not have hookedends at one endof the fabric for connection-of the helical springs and looped ends atthe other end, that is Vit does not have one forma# tion at one end ofthe fabric and a different formation at the other. On the contrary theends of the'fabric at both ends thereof are L similarlyformed for the,connection of the i helical springs or any otherV form of connectionthat may be desired to be used.

When the loop portion 6 or 7 (see Flg.

Y comes at the outer edge of the fabrica Fig. l.

v crease the resiliency of the links or units,

whichresiliency is also very much assisted bythe N-shaped formation ofthe links while at the same time a straight pull by reason of thestraight parallel portions each terminating in a hookV orloop isobtained and maintained.
